Microencapsulation of bisneopentyl glycol dithiopyrophosphate and its flame retardant effect on polyvinyl alcohol

Flame‐retardant poly (ethylene terephthalate) enabled by a novel melamine polyphosphate nanowire

“…Moreover, two distinct absorptions belonging to CH 2 at 2987 and 2880 cm −1 were also detected, indicating the existence of aliphatic species. For PET/FR5.0 nanocomposite, new absorption peaks appeared at 1071 and 1158 cm −1 , which resulted from the occurrence of P–O–P bond and the stretching vibration of P═O group, respectively, revealing the formation of polyphosphoric acid and organic phosphate compounds …”

“…phosphate compounds. [37][38][39][40] The XPS provided abundant information of elementary composition of char residue for PET and PET/FR5.0 nanocomposites, which supplemented the obtained FT-IR results. Figure 10B-F exhibited the XPS spectra survey for all samples.…”

Flame-retardant mechanism of a novel polymeric intumescent flame retardant containing caged bicyclic phosphate for polypropylene

“…could be detected [25e27]. The phosphorus-containing compounds could quench the free radicals like H$ and OH$, while the incombustible gases (H 2 O, CO 2 and NH 3 ) diluted the flammable products and simultaneously reduced the heat of the flame [28]. When the temperature increased to 408 C, a maximum signal intensity was observed.…”

Fabrication and origin of new flame retarding bismaleimide resin system with low dielectric constant and loss based on microencapsulated hexaphenoxycyclotriphosphazene in low phosphorus content

“…When the temperature is lower than 450 C, the mass of MH7/BD is less than that of BD resin because of the decomposition of the phosphorus-containing compound; however, the former is still higher than that of HPCTP7/BD resin. After stayed at 450 C for 15 min, the peak assigning to the PeOeC [43] is also observed, so the phosphorus-containing compound in the MH7/BD resin has high thermal stability. When the temperature is increased to 500 C, new peaks attributing to PeOeP and P]O (1383 and 1029 cm À1 ) appear (Fig.…”

“…The reductions of THE/TML and EHC values indicate flame inhibition or fuel dilution [4,11,27,43,47,48]. Table 3 shows that compared to BD resin, HPCTP/ BD resins have slightly low EHC values, while MH/BD resins have obviously lower ones, meaning that MH/BD resins have more obvious flame retarding effect in the gas phase than HPCTP/BD resin.…”
